Steven Avery’s new legal team said they plan to present new evidence and are "confident" that the man whose murder case was spotlighted in the documentary "Making a Murderer" will have his conviction vacated.

“We are continuing to examine every aspect of Mr. Avery’s case and all of his legal options,” Kathleen T. Zellner said in a statement Monday. “We are confident Mr. Avery’s conviction will be vacated when we present the new evidence and results of our work to the appropriate court.”

Kathleen T. Zellner & Associates, P.C. in Downers Grove announced Friday it will assume “the full and complete representation of Steven Avery.”

“The Zellner Law Firm is looking forward to adding Mr. Avery to its long list of wrongful conviction exonerations,” the firm said in a statement.

The firm will join Wisconsin counsel Tricia Bushnell, the legal director of the Midwest Innocence Project, the statement said.

Details on how the legal team plans to move Avery's case forward were not immediately clear.

Avery made national headlines in 2003 when he was freed after nearly two decades behind bars -- exonerated for a sexual assault that DNA proved he didn't commit. Two years later, Avery and his then-teenage nephew Brendan Dassey were charged in the killing of photographer Teresa Halbach, who visited the Avery family salvage yard to take photos of a minivan on Halloween.

The documentary strongly suggests the possibility that Manitowoc County sheriff's deputies planted evidence against Avery, including a key found in his bedroom and blood found in the victim's vehicle. But Sheriff Robert Hermann has denied that claim.

"They did not plant evidence," Hermann said. "I trust them 100 percent. Quite frankly, I think justice was served in this case."

Authorities involved with the Wisconsin case are saying the series is slanted and omits crucial facts that led to Avery and Dassey being found guilty in the death of Halbach.

The filmmakers, meanwhile, are standing by their work that spans nearly a decade and largely concentrates on the defense and perspective of Avery and Dassey's relatives.

Lawyers with Northwestern University’s Center for Wrongful Convictions of Youth are currently awaiting a ruling on a Habeas petition filed on behalf of Dassey, hoping to force a new trial in his case. They have argued that Dassey’s trial was plagued by the actions of his former attorney, who was removed from the case, and claim that Dassey’s confession was coerced.
